COAL TUNNEL CARBON MONOXIDE SENSING USING DRAEGER DETECTORS SUPPORTS PLANT SAFETY
Neal Systems deployed a coal tunnel carbon monoxide monitoring system at a New Jersey-based clean coal-burning power plant. The new system uses sixteen Draeger carbon monoxide detectors to monitor ambient air in a conveyor belt tunnel situated beneath the plant’s stockpile of several thousand tons of coal. The intense mechanical pressure exerted on coal at the pile’s bottom can potentially cause this coal to emit toxic levels of carbon monoxide, thus compromising tunnel safety. The system warns personnel of toxic conditions in the tunnel via strategically-placed alarm sounders and strobe beacons, driven by a centrally located Alarm Controller. A 15” color interface at the entrance allows personnel to view a videographic map of the entire tunnel complex, highlighting each carbon monoxide detector’s physical location, real-time concentration measurement, and alarm status. This enables operators to evaluate tunnel conditions at a glance without having to enter it. Ethernet communications provided by the Alarm Controller’s Ethernet switch also made possible the system’s follow-on connection to the plant’s primary DCS.
CELLULAR TECHNOLOGY IMPROVES WATER LEVEL MONITORING WITH COST SAVINGS
Neal Systems helped a Susquehanna River power plant monitor water levels 15 miles upstream using a Bluetree cellular modem and several Sixnet components. This eliminated their need for expensive phone lines while improving the reliability of communications in poor weather.
CHESSEL DATA ACQUISITION UPGRADE ENHANCES MONITORING, RECORDING, & SECURITY
Neal Systems helped a New York power plant transition from Chessell 5000 series recorders to 6000 series, giving users math calculations and visual graphs that can be downloaded into their SCADA System. The 6000 Security Manager option will also help them respond to security issues in their system.
